dynamic-fees

An experimental ERC20 token implementing adaptive tokenomics through an auto-adjusting transfer tax. The contract monitors recent transfer volume in a configurable time window and dynamically increases or decreases fees based on market activity. A clean, dependency-free demonstration of self-regulating, volume-responsive economic design.

Goldsky subgraph for Spry, the dynamic-fee Uniswap V4 hook. Indexes pools, per-swap tier-aware fees, and the hook's fee-curve telemetry for LP analytics.

Uniswap v4 hooks you can build — licensed Solidity excerpts, permission bits and GitHub permalinks for TWAMM, limit orders, dynamic fees, oracles and MEV protection. Built for humans and agents.

Experimental Uniswap v4 dynamic-fee research hook; unaudited and not production LP protection.

Adverse-selection-aware dynamic fees for Uniswap v4 — holdout-validated (P1/P2/P3), live on testnet, 100k-step fuzz clean. Full research arc public: fail + pass.

Directional adaptive-fee Uniswap v4 hook using delayed signed markout and Reactive Network

A Uniswap v4 hook that sets the LP fee from the pool's realized volatility to reduce loss-versus-rebalancing (LVR). Solidity/Foundry, with an LVR simulation harness measuring the effect on real mainnet pools.

Uniswap V4 hook that dynamically adjusts swap fees based on real-time pool volatility using an EWMA model. Calm market → 0.05%. Volatile market → 1.00%. No oracle, no off-chain data — pure on-chain math in a single beforeSwap callback. Deployed on Sepolia.
